All of them were moved to the root location and Sdcard 0 is emty and can not copy anything to it as well as to install apps in it. All the call function is lost as well, only wifi is still working.

I flashed it with Uk stock rom from sammobile and it did not come with pit file.
The point is it was disconnected accidentally while flashing. So, flashed again
with HK stock rom.

Did you try to flash 4.1.2 over 4.2.2 by any chance? They moved the sdcard files to data/media/0 instead of data/media in 4.2.2.
Anyways to best way to fix this is to back up ur sd card to computer and Odin flash the original ROM that came with your device. (LTE hong kong version)

I did but it can not be fixed. It seemed to be lost something.

Flashing 4.1.2 over 4.2.2 is generally not a good idea. It will work if you first copy your sd card to the proper place before you flash a rom. For 4.2.2 it needs to be in data/media/0 folder. For 4.1.2 it needs to be data/media. It is possible to do this with a file manager with root access.
Odin will wipe your internal storage this is normal. The data/media/0 folder is not suppose to exist for 4.1.2 so it doesn't know how to deal with it. You need to format it back to 4.1.2 standards. As far as calls not working you probably need to make sure you have the right settings for calls and data to work. Odin should reflash the modem unless something went wrong during flash.
You should be careful when flashing things with Odin. Odin has total access to your device. Especially since HK ROMs are very different from the ones from UK. Make sure you got the correct .tar.md5 for your device. Check this list: http://samsung-updates.com/device/?id=GT-N5120 This is for N5120.
Good Luck. Worse comes to worse you may needs to triangle away and send to samsung.

Do you still get IMEI in place? If not, the call function would not work. Are you in HK or UK?
As suggested by nickdollahz, you need to copy out all the important files from "root" directory. Then, factory reset and flash again. Please note that factory reset will delete all your data.
For your reference, I'm in HK and has flashed the UK 4.2.2 rom previously (now the Germany one). I retain the original modem file of HK since I'm not sure if the modem of UK is compatible with HK's.

In the dialer, type *#06#, or in setting->about device->status->IMEI, it will display the IMEI no. Is it the same as that in the box?
Please also advise your current baseband and phone version in setting->about device.

That's why the call function does not work.
Please also advice the build number (i.e. last entry in setting->about device) of your current phone.
Before you flashed to 4.2.2 UK rom, what is your HK rom version? It should be N5120ZHBMD7, N5120ZHBME1 or N5120ZHBMG3.
Which version of 4.2.2 UK rom did you flash? And which HK rom version did you flash again?
Do you have EFS backup? If so, when did you back it up?

There may be two possible cases:
1) The EFS is corrupted. If this is the case, since you do not have backup, what you can do is to reset flash counter, factory reset and bring it back to Samsung service center.
2) the EFS is not corrupted and is simply a compatibility issue. I read from i9300 forum that Samsung has changed the format of EFS since July. However, I'm not sure if this is the case for n5120. You may consider to flash the UK rom again and see if the IMEI comes back.
You may try (2) and if bad luck, you can flash back to HK rom and do (1) above.
Good luck!

[Q] IMEI problem with Note 2

I have IMEI problem with my phone. I flash 4.3 via Odin, but this version is full with bugs. After that i flash with 4.1.1 and the problems start. My IMEI became 0049.. After this flash I flash with 4.1.2 - 4.3 but the IMEI is 0049.. I have EFC folder on my PC, but i don't know how to reset her.. I have and other problem, on my screen i have square with info for my phone - PDA ,CSC,BAND,MEMORY and other.
Can you help me to fix this big problem for me..

no one can help u to solve your problem... no one also don't care about this..
this is the kind of oldest radio board on the device. latest modem & kernel only can read new radio hardware. that's why it cannot detect the IMEI correctly..

Try flashing dmg1 rom

You should always always backup every partition. Especially efs.
Anyhow, what service are you trying to use? GSM or CDMA?
If your using it with GSM, and If this phone is truly a sprint phone, it probably got sim locked when he fixed it. I ain't no expert but it probably needs unlocked if this is the case.
Edit: I just understood what you wrote, that he already unlocked it. Sorry for misunderstanding.
But if your using it with sprint, maybe it just needs activation updated. I don't use sprint or CDMA so I don't know a lot about that.
But main thing you need to do before anything else. Is make a full back up of your partitions. I always make backup in two.( Which is mainly all you need)
But also there are programs that (I can't remember there names,) make backups of all your hidden partitions, just in case.
I understand I didn't provide you with a definite answer to your problem but hope it can help.

Edit. Are you using sprint stock ROM? What version? Are you sure it's unlocked? If yes, I might be able to help. But I have to gather some info. And get to my PC. Cause I'm testing a ROM right now and am lagging

I have faced the same problem and, managed to solve it. Here is the solution..
1. Download any kk or lp firmware of n910p. Extract the .tar file, get the ' modem.bin' and flash it using Odin. Do it twice, yes, twice. Before flashing the modem, make sure you have unchecked 'auto boot' option in Odin. To turn off the phone after the first flesh, just take off the battery.
2. Download twrp 3.0.1.0 for n910f. Yes.. TWRP recovery for N910F ( or the model specified under the battery). Flash it using Odin.
3. Download any stock based custom ROM which is based on the modem you have flashed. For example, BOB7, COG5 , COK1( these are the last 4 characters of the stock firmware/modem)
4. Flash the custom ROM using twrp, flash gasps, and smile.
If you face bootloop, just try different kernel. I'm using BOB7 modem, emotion kernel, vision x custom ROM.

also i am on Stock 5.1.1 lollipop
I think the only way u can help me is by sharing a good QCN and EFS for N910P ! (if the above solution from our friend doesnt work 4 me )
Also i am from another country so there is no harm for you if u share it with me in private.
